On July 30, 2026, Thailand's gold market witnessed a historic moment: the domestic buying price of gold bars broke through 38,500 baht per baht-weight (15.244 grams), while the selling price of ornamental gold reached 40,200 baht, both hitting record highs. The key driver of this surge was not a spike in international gold prices, but the continued depreciation of the Thai Baht against the US dollar, triggering safe-haven buying by domestic investors.

Weaker Baht Intensifies, Gold Prices Rise

Since July, the Thai Baht has depreciated approximately 3.2% against the US dollar and broke below the 34 baht per dollar mark this week, the lowest level since 2024. The Bank of Thailand (BOT) issued a statement this morning saying it will closely monitor market fluctuations and intervene if necessary, but did not provide a specific action timeline. Market analysts believe the Baht's weakness is mainly due to two factors: slowing export growth in Thailand, with the July manufacturing PMI preliminary reading falling to 49.8 below the expansion threshold, and the US Federal Reserve maintaining high interest rates, pushing the dollar index back above 104.

The Thai Gold Traders Association (TGTA) noted that international gold prices only rose 0.8% this week, hovering around $2,750 per ounce, but gold prices denominated in Baht surged due to the exchange rate depreciation. Association Chairman Somchai Phichaiyarakul said, "Investors are viewing gold as a hedge against Baht depreciation, causing the domestic gold premium to widen to $25 per ounce, a two-year high."

Safe-Haven Buying Surges, Physical Gold Demand Soars

Gold retailers in Bangkok's Chinatown reported that sales of ornamental gold and gold bars surged 40% over the past week compared to the same period last month, with gold bars being the most popular. Some investors even purchased over 5 kilograms at a time. An unnamed jeweler revealed, "Many customers are converting Baht deposits into gold, because bank deposit rates are only 1.5%, while gold has risen 12% in Baht terms this year."

The gold ETF listed on the Stock Exchange of Thailand (SET)—the GOLD fund—also saw significant capital inflows this week, with net inflows of 230 million baht on July 29 alone, the second highest daily record for the fund this year. Analysts believe this reflects retail and institutional investors participating in gold safe-haven through ETFs.

Linkage Mechanism between Exchange Rate and Gold Prices

Domestic gold prices in Thailand are determined by international gold prices (denominated in USD) and the USD/Baht exchange rate. When the Baht depreciates, even if international gold prices remain unchanged, gold prices in Baht terms rise. Conversely, if the Baht appreciates, it will suppress domestic gold price gains. Therefore, for Thai investors, gold not only hedges against geopolitical risks and inflation but also directly counters domestic currency depreciation.

Historical data from the past decade shows a correlation coefficient of up to 0.85 between the USD/Baht exchange rate and Thai gold prices. When the Baht depreciates by more than 5% annually, domestic gold prices rise an average of 15%, far exceeding the average rise in international gold prices. This characteristic makes Thai gold a unique "dual safe-haven" asset.

Future Trend Forecast: Exchange Rate Remains Key

Looking ahead to the second half of the year, analysts have divergent views on the Baht's trajectory. The research team at Kasikornbank estimates the Baht may further weaken to 35.5 per dollar by year-end, mainly due to widening trade deficits and capital outflow pressures. However, Krungthai Bank believes that if the Bank of Thailand follows through with rate hikes, the Baht could rebound to 33.

On international gold prices, most institutions remain optimistic about medium- to long-term performance. Goldman Sachs' latest report raised its year-end 2026 gold price target to $3,000 per ounce, citing continued central bank gold purchases and expectations of Fed rate cuts. If this forecast materializes and the Baht remains weak, Thai domestic gold prices could challenge 45,000 baht per baht-weight.

However, experts also warn investors to be aware of exchange rate reversal risks. TGTA advisor Nuttapong Sirikul noted, "If the Baht suddenly strengthens, domestic gold prices could drop sharply, and the gains from exchange rate in previous months may quickly evaporate. Investors holding gold ETFs or bars may consider pairing with forward foreign exchange contracts to lock in rates or diversifying part of their assets into dollar-denominated gold products."

Investment Strategy Suggestions

  • Short-term traders: Closely monitor signals of BOT intervention in the currency market and the international gold support level at $2,700. If the Baht breaks below 35, go long on Thai gold bars; if intervention occurs to stem depreciation, reduce positions.
  • Medium- to long-term allocators: Maintain gold at 10%-15% of the investment portfolio to hedge against structural Baht depreciation. Use SET's GOLD ETF or directly purchase gold bars to lower costs and storage concerns.
  • Safe-haven seekers: Consider buying Thai ornamental gold, but note that it includes labor fees and depreciation, with lower premiums upon liquidation. Gold bars or coins are purer safe-haven tools.

In summary, the depreciation of the Thai Baht has become a major force pushing Thai gold prices to record highs. While enjoying gold price increases, investors must not ignore the volatility risks from exchange rate reversals. In the coming months, the BOT's monetary policy moves, US economic data, and international gold price trends will all interact to affect the performance of the Thai gold market.
